1F Multi-RS with Solar on AC-IN

[F.Hoogeveen]

Hi,

I have a 1F Multi RS 6000 with, on AC-IN1, 3 st grid‑tied solar installations connected.
There is an ABB B23 kWh meter in between to pass the energy data to the VenusOS via Modbus.
However, the kWh meter does not appear in VRM, and I also don’t see it included in the DESS calculation.
Do I have a setting wrong, or am I trying to do something that isn’t possible?

As an addition: if I set the location of the solar installations to AC‑OUT, they do become visible.
but the calculation is then incorrect, VRM assumes a much higher load than is actually the case.

Is there a reason why you haven’t used the rs485 to usb usual method?

thanks for your reply.

I’m familiar with this manual and have followed all the steps. I can see the kWh meters in the device list, but they don’t show up as “Solar” on AC Input 1.

Because of this, the VRM overview and the DESS calculations are missing the solar data.

On AC-out setting the become vissable: *only the calculations are wrong..
